Answer from Dailycarcurator

Cold weather causes tire pressure to drop, which can trigger your car's Tire Pressure Monitoring System (TPMS) light.

Tires lose about 1 PSI for every 10-degree Fahrenheit drop in temperature. When the air inside your tires cools, it contracts, leading to lower pressure. If this drop causes the pressure to fall below the minimum threshold set by your vehicle's TPMS, the warning light will illuminate.

This information is for general guidance; always consult your vehicle's owner's manual for specific recommendations.

What is a tire inflator?

A tire inflator is a device used to add air to your vehicle's tires. They can range from small, portable electric pumps that plug into your car's power outlet to larger, more powerful compressors.
